Two-dimensional simulation of water movement in soil in the geotechnical engineering using finite volume method.

The purpose of this research is to simulate close to reality how water moves in the soil in geotechnical engineering issues, which has a special importance and position. Over the years, several numerical methods have been proposed to solve the general equation of water flow in the soil, but in this study has been tried to use the Richard equation and the Crank-Nicholson separation technique and the finite volume numerical method to move water in Soil to be analyzed. For this purpose, two widely used and important issues have been examined. In the first problem, estimating how water moves behind the excavation wall in areas where the groundwater level is high, and in the second problem, how water moves between two subsurface drains at the same depth when the water level rises due to rainfall.
